Researchers from Florida Atlantic University, US, have found a new pathway in the brain associated with the behavioral symptoms of autism spectrum disorder (ASD) and a drug to quell these symptoms.

The drug treated the behavioral disruptions in mice with autism. Scientists believe that it may have the same effect for adults with the condition.

Firstly, 25 years ago, it was discovered that a genetic mutation interferes with the serotonin regulation in people with autism. Serotonin is a key neurotransmitter to the feeling of happiness and plays important role in social functioning.

Then, a particular enzyme was found that had a drastic effect on the reabsorption of serotonin. After that, an experimental compound called MW150 was developed and tested on mice.
